Open, Video- and Robot-Assisted Thoracoscopic Lobectomy for Stage II-IIIA Non-Small Cell Lung Cancer.

ABSTRACT

BACKGROUND: This study compares the short- and long-term outcomes of open vs robotic vs video-assisted thoracoscopic surgery (VATS) lobectomy for stage II-IIIA non-small-cell lung cancer (NSCLC). METHODS: Outcomes of patients with stage II-IIIA NSCLC (excluding T4 tumors) who received open and minimally invasive surgery (MIS) lobectomy in the National Cancer Database from 2010 to 2017 were assessed using propensity score-matched analysis. RESULTS: A propensity score-matched analysis of 4652 open and 4652 MIS patients demonstrated a decreased median length of stay associated with MIS compared with open lobectomy (5 vs 6 days; P < .001). There were no significant differences in 30-day mortality, 30-day readmission, or overall survival between the open and MIS groups. A propensity score-matched analysis of 1186 VATS and 1186 robotic patients showed that compared with VATS, the robotic approach was associated with no significant differences in 30-day mortality, 30-day readmission, and overall survival. However, the robotic group had a decreased median length of stay compared with VATS (4 vs 5 days; P < .001). The conversion rate was also significantly lower for robotic compared with VATS lobectomy (8.9% vs 15.9%, P < .001). CONCLUSIONS: No significant differences were found in long-term survival between open and MIS lobectomy and between VATS and robotic lobectomy for stage II-IIIA NSCLC. However, the MIS approach was associated with a decreased length of stay compared with the open approach. The robotic approach was associated with decreased length of stay and decreased conversion rate compared with the VATS approach.
